I am travelling a lot and also receive a lot of e-mails. Often, I have only a
couple of minutes of connection time to synchronize.

Therefore, I would like to prioritize Send during Send/Receive process - is
it possible to do something like that? (I am aware of "Send All" option).

My Outlook is set to Offline mode, as that is the most convenient for me.

Best regards,
Branko
